343: 49 × 7 = 7^2 × 7 = 7^3
125: 25 × 5 = 5^2 × 5 = 5^3
x^12(7x+5)(49x^2 -35x + 25)
x^12(7x+5)(7x-5)^2
Answer:
Second option is correct
Step-by-step explanation:
Given:
Central angle = 15°
Radius of the circle = 9 in
Arc length = ?
Given formula is
Where n is the central angle of the sector.
Write the given formula for Arc length of the sector.
We know that the the circumference of the circle is , where r is the radius of the circle,
Now we substitute central angle value and radius value in above equation.
----------(
)
Divide the numerator and denominator by 5.
Therefore the arc length of the sector is
